Cheiloscopy and dermatoglyphics in normal and obese individuals: A study in Indian subpopulation.

BACKGROUND

The prevalence of obesity has been steadily increasing worldwide. Reliable and noninvasive tools that can be used to diagnose such conditions may help us in mass screening and prevention. Finger prints and lip prints have been used as the genetic markers in some diseases such as diabetes mellitus. Studies to correlate a possible association of such markers among obese individuals have not been reported in India to date. The present study was conducted to determine and compare the lip print and finger print patterns in normal and obese individuals and also to evaluate any possible correlation between the lip prints and finger prints in both the study groups.

METHODOLOGY: Lip and finger print patterns of 100 obese and equal number of age- and sex-matched healthy individuals were analyzed. Right thumb, right index, left thumb and left index finger prints were evaluated. Gender-wise comparison was also made.

RESULTS

Lip prints revealed no significant difference between obese and nonobese individuals. Predominant Type I lip print was observed in both the study groups. Comparison of finger prints between obese and nonobese individuals revealed a highly significant results for all the fingers. Predominant finger print patterns in the right thumb, right index, left thumb and left index among obese individuals were whorl (51%), loop (83%), whorl (79%) and arch (74%), respectively. No correlation between the lip prints and finger prints was noted.

CONCLUSION

Finger prints in the obese individuals showed significant differences when compared to the normal controls while lip prints failed to reveal any significant difference. Lip prints did not correlate with the finger prints. Right thumb revealed a significant gender difference among obese individuals.
